Miguel Montero hit a game-ending RBI single in the 13th inning, and the Chicago Cubs rallied for a wild 8-7 victory over the Pittsburgh Pirates on Monday night.
Dexter Fowler, Kris Bryant and Anthony Rizzo set the stage for Montero's clutch swing with consecutive RBI singles against Jeff Locke (9-8), plating the tying run. After Ben Zobrist was walked intentionally, Montero lined a clean single into left field.
Rob Zastryzny (1-0) got his first major league win despite allowing Josh Harrison's sacrifice fly in the top half of the inning. Jorge Soler and Willson Contreras homered for the Cubs, and Javier Baez collected four hits.
Pittsburgh had won eight straight road games. It fell 1 1/2 games back of St. Louis for the second NL wild card.
Kyle Hendricks (12-7, 2.19 ERA) and Pirates RHP Chad Kuhl (3-1, 3.50 ERA) get the ball for the second game of the series on Tuesday night. Hendricks is 3-0 with a 1.53 ERA in five August starts. Kuhl allowed two runs and five hits in 6 1/3 innings in a no-decision in his previous start Thursday at Milwaukee.
